Well, to factor out we have to find the gratest common factor of 54 and 24 which is 6. then divide both numbers by that number
54/6=9 24/6=4
6(9a+4b) is your final answer
Answer:
21 minutes
Step-by-step explanation:
30%=9
10%=3
100%-30%=70%
7×10%=70%
3x7=21
=21minutes
The number is = 10x+y
if reverse the digits, the number is: 10y+x
The sum fo its digits is = x+y=5
I suggest this system of equations:
(10y+x)-(10x+y)=27 ⇒9y-9x=27
x+y=5
We can solve this system of equations by equaliztion method
x=5-y
9y-9(5-y)=27
9y-45+9y=27
18y=27+45
18y=72
y=72/18
y=4
x=5-y
x=5-4=1
The number is: 10x+y=10(1)+4=14
Answer: the number is 14
Answer:
118°
Step-by-step explanation:
the angle measures of a triangle will always add up to 180
so..
42+20=62
180-62=118
